SUPPORT FOR CASEMENT-WINDOWS.

SPECIFICATION forming part of Letters Patent No. 703,401, dated July 1, 1902. Application filed December 9, 1901. Serial No. 85,232. (No model.)

T0 at whom it ntcw concern;

Be it known that we, ANTON GNEZDA and FRIEDRICHHAOKER, citizens of Austria-Hungary, residing at Agram, in the Province of Croatia, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Supports for Casement-WindoWs, of which the following is a full, clear, and exact specification.

For supporting open casement windows known as French Windows screw-supports have hitherto been generally used. These supports were moved underneath the open windows and then suitably adjusted. During the opening of the window the latter received no supportwhatever or only a very slight amount of support from the person opening it. Owing to the considerable weight of French windows the latter rest very heavily upon the lower part of the window-case, so that they can only be opened by a comparatively powerful pull or push, and this frequently results in the breaking of the sash, hinges, or glass. The usual method of support is not sufficient even in a moderate wind, since the folding frames can be considerably shaken, which fact increases the danger of breakage.

The present invention relates to a simple device by means of which the folding frames are supported and guided from the beginning of the opening operation, and this device is preferably so arranged that before the opening of the window the folding frame is given a lift by which its under part is raised from the window-case and the opening of the window facilitated. During and after the opening of the window the folding frame is supported and guided on two sides, on one side by the hinges on which it moves and on the other side by the guiding and supporting-device described hereinafter, so that its weight never acts upon one side only, and the hinges are thus considerably relieved.

The annexed drawings represent one form of the new device.

Figure l is a side view thereof, partially in section, on the line 00 :1: of Fig. 2. Fig. 2 is a plan view, partiallyin horizontal section. Fig. 3 represents a front view of the device, and Fig. t represents the latter folded when not in use. Fig. 5 shows a method of mounting the support in the window-casing; and Figs. 6 and 7 are an elevation anda plan View, respectively, of a modified form of a detail of the mechanism.

The essential parts of the device are a support a, which can be introduced into asocket in the window-case and moved horizontally, and a roller 1) or a block or the like fastened to the folding frame of the wi dow. When the latter is opened, the said roller 01' the like will move along the support a and part of the weight of the window willbear upon the said support. The support a, which is formed by a horizontally-moving lever,.is provided with a pin or gudgeon c at one end, which enters a socket d in the window-case. A knob or elevation at the other end of the support prevents the roller b from leaving the latter.

The support a is held in its horizontal position by a stay or strut f, which is preferably pivoted to the said support at one end and supported at the other end by a pin or gudgeonx which enters a bracket h, fastened to the window-case.

The whole supporting device can swing to the right or left on the pivots c and g, and thus move with the roller 1) when the Window is opened or closed, so that in any open position of the window the latter is supported by the said device.

To provide for the perfectly accurate guiding of the window on'the support, the roller 1) may be arranged to move on a vertical pivot 1', Figs. 6 and 7, besides revolving on its axis; but it is sufficient for ordinary purposes to provide the said roller with a suitably wide groove to prevent it from sliding off: the check-support.

In view of the fact that the windowin consequence of its considerable weight rests firmly upon the base of the window-case and that a comparatively large amount of force is required to overcome the friction resulting from this fact, it is desirable to slightly lift the window before it is opened. For this purpose the socket in the window-case for support a is so arranged with regard to the roller 1) that when the support is moved into a horizontal position it will press against the ICO roller 1) from below and sli htly raise the latter, thus also lifting the window. The win (low, which will then rest freely on its hinges and the support, can therefore be opened evenly and smoothly without any special amount of force or sudden jerk, and the danger of breaking the Window in openingit will be reduced to a minimum.

The support a is preferably arranged at approximately half the height of the window, since this prevents the swinging of the latter and causes an approximately equal area of surface to be exposed to the wind-pressure above and below the support.

When the support is not in use, it can easily be folded, Fig. 4. If desired, however, it can be made in the form of a rigid triangular support, in which case it cannot be folded.

Having now described the nature of our inments, a roller on the swinging sash having a.

bearing on the lever, and a brace-rod pivoted at one end to the lever and provided at the other end with a pin 9 pivotally mounted on the frame, the said pin g serving as a pivot for the brace-rodin the horizontal movements of the latter.

In testimony that We claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
